MainInt

Mainint is a term that appears sporadically in programming tutorials and informal discussions, but it is not established as a standard concept in computer science. When it occurs, it usually refers to the main integer input or the primary integer value manipulated by a program, rather than a formal language construct.

Etymology and naming. The term combines "main" and "int" (short for integer). Because it is not a reserved word in any major language, capitalization and spelling vary (for example, mainint, MainInt, mainInt) depending on the conventions of the source material.

Common usage. In introductory material, mainint may appear as a placeholder name for a variable that holds the primary integer value read from standard input or from a data source. It is often used in pseudocode or example code to illustrate input handling, type declarations, or arithmetic operations involving integers.

Relation to other concepts. It should not be confused with the main function of a program or with the int data type itself. "Mainint" is not a standard term; in real code, developers would use descriptive identifiers such as mainInput, userValue, or n.
